| 説明 | Busycon sinistrum Hollister, 1958 - lightning whelk (public signage, Bailey-Matthews Shell Museum, Sanibel Island, Florida, USA)This species is also known as Sinistrofulgur sinistrum, which has been considered by some to be conspecific with Busycon perversum.The gastropods (snails & slugs) are a group of molluscs that occupy marine, freshwater, and terrestrial environments. Most gastropods have a calcareous external shell (the snails). Some lack a shell completely, or have reduced internal shells (the slugs & sea slugs & pteropods). Most members of the Gastropoda are marine. Most marine snails are herbivores (algae grazers) or predators/carnivores.The museum signage shown above depicts a female lightning whelk producing a long, spiral egg case.Classification: Animalia, Mollusca, Gastropoda, Neogastropoda, Busyconidae-------------------More info. at:en.wikipedia.org/wiki/Sinistrofulgur_sinistrum |
